Drayton Wiser Smart Heating Radiator Thermostat Works with Amazon Alexa, Google Home, IFTTT

Product Information

Both Vaillant and Worcester use load compensation making the combined TRV and smart control set up incredibly efficient once mounted you should just need to turn the TRV to the right for 2 seconds,you should hear the TRV close and that's the calibration complete require a combined programmer and thermostat with an ‘advanced’ energy saving feature. Namely: weather compensation, load compensation or smart controls that combine automation and optimisation features. (Or you can fit a flue gas recovery unit.) New installations of a heat only or system boiler: must have ‘time and temperature controls’ namely a programmable room thermostat or a thermostat with separate programmer. You can still opt to install an advanced control. Existing boiler installations: The Heat Hub is a rectangular box with two buttons. One button activates the set-up process, while the other starts the whole system heating. LEDs above the buttons glow green when these options are active. The Heat Hub should be screwed to the wall next to your boiler. The square smart thermostat has a two-inch screen that shows the current temperature of the room it’s in, as well as the desired temperature. It also displays the relative humidity and battery level, and features a flame icon to indicate if the heating is switched on.

From the home screen, you can also view the weather for your location and sunrise and sunset times, too. The cog icon at the top of the home screen provides access to the main Settings menu, from where you can activate smart modes such as Eco and Comfort, and set a temperature for the Away mode. In general, somewhat disappointed with the control characteristics of the system, can only describe the radiator stat's action as "on/off" control, can not see any attempt at achieving "proportional" action as was quite normal with the old dumb TRV's they are replacing, radiators are either piping hot or off, no modulated "in between" point.Calibrate the TRV by turning and holding it to minus (the blue LED). The TRV pin should descend onto the valve pin and close off the valve. Wiser is straightforward to install and even easier if your current controller is mounted on a standard wallplate and you have existing Thermostatic Radiator Valves (TRVs). I've been reinstalling our Wiser TRVs recently as we are going through the phases of a home renovation and had similar problems to yours OP, now resolved. The TRVS replaced old Danfoss ones, which was an easy swap. They have connected to the system without issue. However the living room one, even when I put it on boost, will not allow the radiator to warm up. I can hear the solenoid open so should allow hot water to flow but it will not warm up The third-party smart TRVs reviewed here all do much the same thing, it is the control thermostat that is the most important choice. The Honeywell EvoHome is suited for much larger properties. All six other thermostats are compatible with the vast majority of heating systems (old and new boilers) and will operate the boiler efficiently based on a learned pattern of when you need heat.

Neither of the boiler manufacturer's smart TRVs are compatible with home automation devices such as Alexa, IFTTT and Google Home. rejoin the valve via Settings - Devices - "+" button - radiator valve - twist top to + until led flashes green. If it fails first time, wait for valve to time out, close and reopen app and try again, it can be hit and miss If you use the boiler manufacturer's own smart TRVs you only have to deal with one manufacturer for all your heating system products Yes, when a TRV from another room (lets call it room 2) drop below its setpoint temperature it will call for heat and the boiler will turn on to heat that room. If you only have dumb TRV's in the room with the room stat (lets call this room 1) then when Room 2 is calling for heat then Room 1 will also be heated as it has no way to turn off those radiators while the boiler is on to heat Room 2.I did manage to solve it. It turned out that the firmware of the HUB was old and this was the reason why it was unable to control the TRVs. The same with the bedroom, however it warms up ever so slightly, like as if it was the old Danfoss TRV set to 1 or 2 out of 5. These smart radiator thermostats replace the TRVs (thermostatic radiator valves) on your radiator, the type that let you adjust the temperature of the radiator manually. If you don’t have TRVs then you’ll need to bear the cost of changing your current valves to TRVs on top of the cost of the smart heating system. There’s no denying the radiator thermostats are bulkier than TRVs, but we found we didn’t notice them as much as we expected to.

Delete the problem valve via Settings - Devices - select the valve - then "Delete". Your schedules etc won't be lost, this just removes the valve from the systemhave no minimum requirement for heating controls other than those required at the time of installation. Again you can opt for an advanced control. You may only wish to have the functionality of an internet control. Guide to selecting the right advanced controls

The Insights tab includes information on how much energy you’ve saved with Eco mode enabled, while also presenting a ‘Heat Report’ that details how long and to what temperature over the past day, week, and month your rooms have been heated.

Drayton Wiser may be functional, but its plain all-white plastic design certainly isn’t stylish. If you prefer gadgets that make a design statement, this isn’t the smart thermostat for you. You can tap on a room and edit the schedule or access the room settings, where you can view the battery level for the thermostat, rename it and turn Open Window Detection on or off. Editing a schedule was made super-easy as a result of the ‘copy’ feature, which lets you duplicate a schedule with just one tap, rather than having to input it all for each day and on each device. the logic behind smart TRV's is you don't heat empty rooms this only really works if every room has a smart TRV The Drayton Wiser system lets you set a schedule for each thermostat, indicating a desired temperature for each room in your home at different times of the day. For example, you can set the bathroom to warm up first thing in the morning and last thing at night, if you don’t use it during the day. As already mentioned, you can override a set schedule at any time by manually twisting the top of the radiator thermostat (turning the heating on in that room for 30 minutes) or from the app, where you can choose for the heating to remain on for between 30 minutes and three hours.
